# FIND_AND_IMPORT_CMAKE_PROJECT can be used by projects to find other
|
||||
# CMake projects.
|
||||
#
|
||||
# For example, the author of library FOO would include a file called
|
||||
# FOOConfig.cmake in the project's distribution. Usually such a file
|
||||
# would be configured and installed by FOO's CMake code into a
|
||||
# directory such as PREFIX/lib/foo.
|
||||
#
|
||||
# The author of application BAR that uses FOO would include the
|
||||
# following lines in BAR's CMake code:
|
||||
#
|
||||
# INCLUDE("${CMAKE_ROOT}/Modules/FindAndImportCMakeProject.cmake")
|
||||
# FIND_AND_IMPORT_CMAKE_PROJECT(FOO_DIR FOOConfig.cmake lib/foo)
|
||||
#
|
||||
# When CMake is run to build BAR, FOO_DIR will be the only
|
||||
# CMakeCache.txt entry that is needed for FOO. When FOO_DIR has been
|
||||
# set correctly, FOOConfig.cmake will automatically be included to
|
||||
# provide whatever settings are needed to use FOO.

||||
