Installs a config module if CMake verion >= 2.8.12. The config-module creates the import library targets built in the project (glew, glew_s, glewmx, glewmx_s) but in accordance with the FindGLEW module shipped with CMake, it also creates GLEW::GLEW and GLEW::GLEWMX. GLEW::GLEW and GLEW::GLEWMX will be simply copies of glew/glewmx or glew_s/glewmx_s. If both versions are available they alias the shared versions. The default behaviour can be changed either when installing or when using the package: - Set BUILD_SHARED_LIBS to OFF or ON when building and installing GLEW. This controls which libraries (shared or static) will be installed (and not which will be built). - Set GLEW_USE_STATIC_LIBS to OFF or ON before calling `find_package(GLEW CONFIG REQUIRED)` to force the config-module to create GLEW::GLEW and GLEWMX as aliases to glew/glewmx or glew_s/glewmx_s The script ./cmake-testbuild.sh is added to test the CMake build and config-module. See instructions there.

# CopyImportedTargetProperties
|
|
# --------------------------
|
|
#
|
|
# Copies the `INTERFACE*` and `IMPORTED*` properties from a target
|
|
# to another one.
|
|
# This function can be used to duplicate an `IMPORTED` or an `ALIAS` library
|
|
# with a different name since ``add_library(... ALIAS ...)`` does not work
|
|
# for those targets.
|
|
#
|
|
# ::
|
|
#
|
|
# copy_imported_target_properties(<source-target> <destination-target>)
|
|
#
|
|
# The function copies all the `INTERFACE*` and `IMPORTED*` target
|
|
# properties from `<source-target>` to `<destination-target>`.
|
|
#
|
|
# The function uses the `IMPORTED_CONFIGURATIONS` property to determine
|
|
# which configuration-dependent properties should be copied
|
|
# (`IMPORTED_LOCATION_<CONFIG>`, etc...)
|
|
#
|
|
# Example:
|
|
#
|
|
# Internally the CMake project of ZLIB builds the ``zlib`` and
|
|
# ``zlibstatic`` targets which can be exported in the ``ZLIB::`` namespace
|
|
# with the ``install(EXPORT ...)`` command.
|
|
#
|
|
# The config-module will then create the import libraries ``ZLIB::zlib`` and
|
|
# ``ZLIB::zlibstatic``. To use ``ZLIB::zlibstatic`` under the standard
|
|
# ``ZLIB::ZLIB`` name we need to create the ``ZLIB::ZLIB`` imported library
|
|
# and copy the appropriate properties:
|
|
#
|
|
# add_library(ZLIB::ZLIB STATIC IMPORTED)
|
|
# copy_imported_target_properties(ZLIB::zlibstatic ZLIB::ZLIB)
|
|
#
