| Summary | 0012254: Hardcoded CMAKE_SYSTEM_LIBRARY_PATH is no good. |
| Description | The find_library function fails to find libraries not installed in the standard.
And old mailing list entry explained it well.
http://www.cmake.org/pipermail/cmake/2010-January/034747.html [^]
I implemented the recursive checking of ld.so.conf, which fixed the problems for me, and gives CMake a correct behavior on Linux systems.
|
| Steps To Reproduce | 1. Using Debian Sid. New version of glibc places libraries in /usr/lib/x86_64-linux-gnu/ which is overlooked by find_library
2. Configure with CMake and FindMPI will fail to find many libraries such as libld.so, libnsl.so etc.
