Cache entries created by `try_compile` are already `INTERNAL`.
|
|
|
|
|
|
|

As per Intel MKL command line advisor, "libdl" is added to the list of
libraries that provide LAPACK functionality. Furthermore, the implicit
link directories are added to the searched libraries to allow finding
of "libgomp".
|
|
|
|
|
| |
Auxiliary internal variables related to MKL are now consistently
prefixed with LAPACK_mkl_ and unset at the end of the MKL section.
|
|
|
|
|
|
|
|
| |
A surplus library libmkl_gf_... has been removed from the LAPACK
libraries serach path (when relevant, it is already provided by BLAS).
Similarly, the thread libraries do not need to be explicitly added to
the implicit LAPACK libraries, as they are already included in the
list (via BLAS libraries provided by FindBLAS).
|
|
|
|
|
|
| |
As in FindBLAS, the Intel Math Kernel Library is now the preferred
LAPACK vendor. (The corresponding section of the code has been moved
upwards.)

f1a3e4eca8 FindLAPACK: Correct library name and symbol searched in LAPACK95 wrapper

The symbol "CHEEV", originally used to determine if a library provides
Fortran 95 wrappers for LAPACK, has been replaced by "cheev_f95". "CHEEV"
is provided by libmkl_intel_(i)lp64, which does not provide the generic
Fortran 95 wrappers. Instead, libmkl_lapack95_(i)lp64 does; one of the
specializations of the type-generic interfaces contained in that library
is "lapack_f95".
Also, FindLAPACK used libmkl_intel_(i)lp64 instead of the correct
libmkl_lapack95_(i)lp64 library for LAPACK95 functionality. This has
been fixed, too.

Modern Intel MKL packages offer 64-bit BLAS and LAPACK libraries in any
of the eight combinations of the following three binary options:
- sequential or threaded
- LP64 or ILP64
- static or shared
The modules FindBLAS and FindLAPACK did not allow full selection of
arbitrary combination; in particular, only LP64 variant was used.
The original list of possible BLA_VENDOR values related to MKL,
Intel10_64lp
Intel10_64lp_seq
is thus extended by another pair of "vendors",
Intel10_64ilp
Intel10_64ilp_seq
Depending on the selection, either "_lp64", or "_ilp64" MKL libraries
are searched for. Some comments in the two CMake modules were modified
to indicate that even though the "vendors" contain the number "10",
they also apply to all further versions of MKL.

FLAME (github.com/flame) provides a variety of numerical libraries.
`blis` and `libflame` can be setup to expose BLAS/LAPACK interfaces.

Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.

Use `CMAKE_<LANG>_COMPILER_LOADED` to detect enabled languages because
`if( _LANGUAGES_ MATCHES C )` is always true on Windows as the RC
language is activated automatically and matches C.

All these expressions work the same:
"foo"
".*foo.*"
"^.*foo.*$"
This assumes that the "Intel*" expressions were meant to be "Intel.*".

Fixes issues #14812 and #14813 where find_package(OpenMP QUIET) and
find_package(Qt4 QUIET) would still print out messages when calling
check*() functions.
Also a partial fix for #14445 where building CMake
(without cmake-gui) when Qt5 is installed and Qt4 is not installed
and warnings come out of FindQt4.cmake.

Run the convert-help.bash script to convert documentation:
./convert-help.bash "/path/to/CMake-build/bin"
Then remove it.

This solves a lots of warnings, e.g. in the FindModulesExecuteAll test. If the
installed version on the system is rather old this may even lead to bugs, e.g.

Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block. This is no longer the preferred style.
Run the following shell code:
for c in else endif endforeach endfunction endmacro endwhile; do
echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

fixed: CMAKE_FIND_LIBRRAY_SUFFIXES misprint
added: ATLAS vendor to FindLAPACK module
|
|
|
|
|
|
|
|

fixed: saving/changing/restoring CMAKE_FIND_LIBRARY_SUFFIXES variable.
fixed: BLA_VENDORs "Apple" (Accelerate Framework) and
"NAS" (vecLib Framework) fail as 'cblas_dgemm_' doesn't exist.
fixed: improve "Generic" detection on Ubuntu (and I assume Debian)
(work with libblas3gf and liblapack3gf packages).

This adds copyright/license notification blocks CMake's find-modules.
Many of the modules had no notices at all. Some had notices referring
to the BSD license already. This commit normalizes existing notices and
adds missing notices.

have three new variables BLA_VENDOR (you can specify the VENDOR), BLA_STATIC (gets the static version of libs), BLA_F95 (gets the fortran 95 interface). BLA_VENDOR can be specified as an environment variable. Intel mkls libs need FindThreads to be found correctly so you will need to enable the C/CXX

implementations of blas and lapack libraries. CheckFortranFunctionExists.cmake provides a test function to check if the library is usabale. I have also changed the -KPIC flag to -fPIC in Linux-ifort.cmake.
