I have no idea about CMAKE_USE_RELATIVE_PATHS since I have never
needed/wanted to use that however for the other cases that it appears
the CMake does not let me change a value I usually get around this
using the following examples:
SET (CMAKE_INSTALL_PREFIX ${PGM_FILES}/UPMC/${CMAKE_PROJECT_NAME}
CACHE STRING "Default Install Path" FORCE)
IF (MAKE_DEBUGRELEASE)
SET (CMAKE_CONFIGURATION_TYPES "Debug;RelWithDebInfo" CACHE STRING
"Debug;RelWithDebInfo" FORCE)
SET (RELEASE_BUILD_NAME "RelWithDebInfo")
ELSE(MAKE_DEBUGRELEASE)
SET (CMAKE_CONFIGURATION_TYPES "Debug;Release" CACHE STRING
"Debug;Release" FORCE)
SET (RELEASE_BUILD_NAME "Release")
ENDIF (MAKE_DEBUGRELEASE)
The keys are CACHE and FORCE.
