Summary

0010312: FindMPI.cmake fails for path name containing "-l"

Description

Using find_package(MPI) fails on a Linux machine, where the MPI installation is located in a directory containing the string "/mpi-libs/":

CMake Error at [...]/cmake-2.8/Modules/FindMPI.cmake:277 (message):
Unable to find MPI library ibs/[...]/include

While parsing MPI_LINK_CMDLINE, FindMPI.cmake seems to assume anything after "-l" is a library name, even if no whitespace is preceeding the "-l". Similiar issues might arise with the treatment of "-L" and further compiler/linker option strings.

Additional Information

A quick (and dirty) hack in FindMPI.cmake:

265c265
< string(REGEX MATCHALL "-l([^\" ]+|\"[^\"]+\")" MPI_LIBNAMES "${MPI_LINK_CMDLINE}")
---
> string(REGEX MATCHALL " -l([^\" ]+|\"[^\"]+\")" MPI_LIBNAMES "${MPI_LINK_CMDLINE}")
271c271
< string(REGEX REPLACE "^-l" "" LIB ${LIB})
---
> string(REGEX REPLACE "^ -l" "" LIB ${LIB})

solves the issue my case. Of course, this is no acceptable patch yet.

FindMPI sometimes fails because it checks for non-existing libraries

Notes
(0019582) James Amundson (reporter) 2010-02-22 17:38	I hate to say "me, too!", but I am currently experiencing major headaches because of this bug. The only way to work around it is to edit the installed FindMPI.cmake script as suggested above.
