GTestsuite:Search library in user specified-path
Browse files Browse the repository at this point in the history 
In Gtestsuite CMakeLists.txt, find_library() will search
user-mentioned library in default system paths first then
in user specified paths. To avoid this CMake is updated
to search the user mentioned library in user specified
path and ignore searching in default path.

AMD-Internal: [CPUPL-4284]
