* Help: Improve documentation formatting of find_* commandsBrad King2015-06-081-5/+11
| | | | | Use inline reStructuredText markup and add cross-references in more places.
* Help: Document the CMAKE_FIND_ROOT_PATH* variables.Stephen Kelly2013-11-271-5/+5
| | | | | Add a replacement template for the variables, and link to them from the documentation for the find_* commands.
* Introduce CMAKE_STAGING_PREFIX variable.Stephen Kelly2013-11-211-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | This variable can be useful in cross-compiling contexts where the sysroot is read-only or where the sysroot should otherwise remain pristine. If the new CMAKE_STAGING_PREFIX variable is set, it is used instead of CMAKE_INSTALL_PREFIX when generating the installation rules in cmake_install.cmake. This way, the CMAKE_INSTALL_PREFIX variable always refers to the installation prefix on the target device, regardless of whether host==target. If any -rpath paths passed to the linker contain the CMAKE_STAGING_PREFIX, the matching path fragments are replaced with the CMAKE_INSTALL_PREFIX. Matching paths in the -rpath-link are not transformed. The cross-prefix usr-move workaround is assumed not to require extension regarding CMAKE_STAGING_PREFIX. The staging area is a single prefix, so there is no scope for cross-prefix symlinks. The CMAKE_INSTALL_PREFIX is still used to determine the workaround path, and that variable remains the relevant one even if CMAKE_STAGING_PREFIX is used. If the generated export files are deployed to the target, the workaround will still be in place, and still be employed if required.
* Add CMAKE_SYSROOT variable to set --sysroot when cross compiling.Stephen Kelly2013-11-191-2/+9
| | | | | | | | | | As CMAKE_ROOT_FIND_PATH can be a list, a new CMAKE_SYSROOT is introduced, which is never a list. The contents of this variable is passed to supporting compilers as --sysroot. It is also accounted for when processing implicit link directories reported by the compiler, and when generating RPATH information.
* Help: Factor out find_* command duplicationBrad King2013-10-161-0/+14
These documents were represented in the builtin documentation using a common starting point with placeholders substituted by each command. Convert them back to this approach using the reStructuredText include directive and substitutions to avoid duplication.
