I have been trying to get FindPerlLibs to work on windows (Vista). It's
taken me a while but I think I have found the problem. As far as I have
been able to identify the string regex replace call returns (what I
think is) an undesirable result. Below is an example to illustrate the
problem:
SET( TEST_STRING "test stuff libperl='libperl23.lib'" "\n" )
string(REGEX REPLACE "libperl='([^']+)'" "\\1" TEST_OUTPUT_VARIABLE
${TEST_STRING} )
MESSAGE( STATUS "TEST OUT: (${TEST_OUTPUT_VARIABLE})
(${CMAKE_MATCH_0}) (${CMAKE_MATCH_1})" )
where: TEST_STRING is my approximation to the string(s) return from
${PERL_EXECUTABLE} -V:libperl
The output is:
-- TEST OUT: (test sturff libperl23.lib
) (libperl='libperl23.lib') (libperl23.lib)
So the carriage return is the unexpected bit for me, for the
TEST_OUTPUT_VARIABLE. This is why I have put parentheses around the
variables so that I could see hidden characters.
The attached patch is what I came up with to address the problem, plus
some other random stuff that I did whilst trying to ascertain what was
going on. This is a windows patch so don't try and apply it on Linux.
Also, I took this FindPerlLibs.cmake from the CMake CVS repository
recently, like today.
