* cmake: Allow CMAKE_INSTALL_PREFIX to be set by environment variableSilvio Traversaro2024-01-301-0/+11

* Help: Document {CTEST,CMAKE_BUILD}_PARALLEL_LEVEL equivalent command-linescivision2024-01-182-2/+10
| | | | | Clarify that the `--parallel` option isn't needed when these env. variables are set to a finite integer.
* add_test: Optionally use a launcher for tests running in-project targetsRalf Habacker2023-12-131-0/+11
| | | | | | | Add a `CMAKE_TEST_LAUNCHER` variable and corresponding `TEST_LAUNCHER` target property. Issue: #23672
* HIP: Add CMAKE_HIP_HOST_COMPILER when compiler is NVCCBrad King2023-09-251-0/+19

* CrossCompiling: Load CMAKE_CROSSCOMPILING_EMULATOR from environmentMatt McCormick2023-06-131-0/+11
| | | | | | | | | | | Read `CMAKE_CROSSCOMPILING_EMULATOR` from an environment variable of the same name if not specified with `-D` or an initial cache value. Along with existing environment variable settings such as `CMAKE_TOOLCHAIN_FILE`, cross compilation configuration can be more completely set via environment variables.

* Optionally exclude implicit link directories via environmentBrad King2023-05-251-0/+13
| | | | | | | | A misconfigured compiler may pass extraneous implicit link directories to its linker. If they are in `CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES`, CMake may generate extra `-L` flags on mixed-language link lines that break linking. Add an environment variable that users can set to work around such misconfiguration of their compilers.
* Help: add documentation for some CMAKE_XXX_PATH env.varsAlex Neundorf2023-05-015-0/+68
| | | | | | | This patch adds basic documentation for the CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH, CMAKE_PROGRAM_PATH, CMAKE_APPBUNDLE_PATH and CMAKE_FRAMEWORK_PATH environment variables and links to the respective cmake variables and vice versa.
* Add CMAKE_MAXIMUM_RECURSION_DEPTH environment variableBrad King2023-03-131-0/+10
| | | | | | | Extend the recursion limit controls added by commit a6982cff0d (cmMakefile: Impose maximum recursion limit, 2018-12-14, v3.14.0-rc1~82^2) with an environment variable that is used if the CMake variable of the same name is not set.
* find_package: Use <PACKAGENAME>_ROOT variables as search prefixesBrad King2023-02-231-0/+14
| | | | | | | | | Extend commit eb35d8884b (find_package: Use PackageName_ROOT variables as search prefixes, 2018-03-15, v3.12.0-rc1~349^2) to also check upper-case `<PACKAGENAME>_ROOT` variables. Add policy `CMP0144` to enable the behavior in a compatible way. Fixes: #24403
* Help: Clarify that <PackageName>_ROOT variable names are case-preservedBrad King2023-02-081-4/+4
| | | | | The name comes from the case-preserved first argument to `find_package`.
* ctest(1): Add CTEST_NO_TESTS_ACTION env varfriendlyanon2023-01-131-0/+14
| | | | | This environment variable provides a default value for the --no-tests=<action> command line argument.

* Help: Clarify how language-specific flag environment values are usedBrad King2022-10-1810-56/+57
| | | | | | | | | Previous the wording could be interpreted to mean that the environment variables like `CXXFLAGS` are used exclusively to initialize the corresponding cache entries like `CMAKE_CXX_FLAGS`. State clearly that the value will be used in combination with builtin defaults. Issue: #23956
* Help: Disambiguate cmake(1) program modes in Sphinx option referencesBrad King2022-10-051-1/+1
| | | | | | Define the entry point to each mode as an option for the `cmake` program, but reference the options for that mode as part of stand-in `cmake-<mode>` programs.
* cmCurl: Honor OpenSSL certificate environment variablesMaxim Cournoyer2022-09-162-0/+18

* Help: Correct CUDAHOSTCXX and CUDAARCHS as having higher precedenceRaul Tambre2022-01-152-5/+3
| | | | | | | | | | | | | | | | | | | | | For CUDAHOSTCXX the behaviour seems to have been like this since the introduction of it in commit 9cf5b98d ("CUDA: Prefer environment variables CUDACXX and CUDAHOSTCXX.", 2016-11-08) and is likely unintentional judging by the wording of the commit. The documentation mistake seems to be a copy-paste error from when all the environment variables were documented in commit e6b77c5f ("Help: Document CMake's environment variables", 2017-09-01). Describe this explicitly as it is unlike all other similar environment variables. For CUDAARCHS we got it wrong from the get-go in commit c4ae9384 ("CUDA: Initialize CMAKE_CUDA_ARCHITECTURES using $ENV{CUDAARCHS}", 2020-11-24). Correcting either to follow the more standard precedence behaviour will require a policy. Fixes #23081.

* Alternative symlink-creating mode for file(INSTALL ...)Felix Lelchuk2021-08-021-0/+37
| | | | | | | | | | | An new environment variable 'CMAKE_INSTALL_MODE' is introduced, which can be used to ask CMake to create symbolic links instead of copying files during a file(INSTALL ...). The operation is at the file level only, directory trees are still created using actual directories, not links. Signed-off-by: Felix Lelchuk <felix.lelchuk@gmx.de>

| * macOS: Offer control over host architecture on Apple Silicon hostsBrad King2020-12-101-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit b6c60f14b6 (macOS: Default to arm64 architecture on Apple Silicon hosts, 2020-09-28, v3.19.0-rc1~63^2) we use `sysctl` to detect that we are running on Apple Silicon in a way that pierces Rosetta. This always sets `CMAKE_HOST_SYSTEM_PROCESSOR` to be `arm64` on such hosts. However, macOS offers strong support for running processes under an emulated `x86_64` architecture. Teach CMake to select either `arm64` or `x86_64` as the host architecture on Apple Silicon based on the architecture of its own process. When CMake is built as a universal binary, macOS will select whichever slice (architecture) is appropriate under the user's shell, and `CMAKE_HOST_SYSTEM_PROCESSOR` will match. Also offer a `CMAKE_APPLE_SILICON_PROCESSOR` variable and environment variable to provide users with explicit control over the host architecture selection regardless of CMake's own architecture. Finally, if `CMAKE_OSX_ARCHITECTURES` is not set, pass explicit flags to the toolchain to use selected host architecture instead of letting the toolchain pick. Fixes: #21554

|/ | | | | | | NVCC's default architecture may be newer than the one supported by the machine's GPU. In such cases it's useful to have an environment variable for initializing CMAKE_CUDA_ARCHITECTURES to avoid specifying it for every invocation.
