This was my first impression, so I used the ConfigVersion file of http://www.cmake.org/Wiki/CMake_2.6_Notes to be on the safe side. SET(PACKAGE_NAME "TLib") SET(PACKAGE_VERSION 1.3) IF("${PACKAGE_FIND_VERSION_MAJOR}" EQUAL 1) SET(PACKAGE_VERSION_COMPATIBLE 1) IF("${PACKAGE_FIND_VERSION_MINOR}" EQUAL 3) SET(PACKAGE_VERSION_EXACT 1)# exact match for version 1.3 ENDIF("${PACKAGE_FIND_VERSION_MINOR}" EQUAL 3) ENDIF("${PACKAGE_FIND_VERSION_MAJOR}" EQUAL 1) But this also does not work.
