Changeset 2613 for code/branches/buildsystem2/cmake/DetermineVersion.cmake

Timestamp:

Jan 29, 2009, 10:19:15 PM (15 years ago)

Author:

Message:

• Added FindPackageHandleAdvancedArgs.cmake module that invokes FindPackageHandleStandardArgs and then checks the version requirements. Usage: FIND_PACKAGE_HANDLE_ADVANCED_ARGS(NAME MSG VERSION VARS) (like the orginal CMake module, but with the additional version argument)
• Updated DetermineVersion.cmake and HandleLibraryTypes.cmake to use FUNCTION instead of MACRO and also removed CACHE setting of the veriables (unnecessary).

File:

• code/branches/buildsystem2/cmake/DetermineVersion.cmake (modified) (2 diffs)
