[CMake] How to prevent semicolons in pkg-config.pc files generated with configure_file?

[Claus Klein]

Hi

I want to create a pkg-config.pc file with cmake.

claus-kleins-macbook-pro:build clausklein$ pkg-config --libs QtOpenGL
-L/opt/local/lib -lQtOpenGL -lQtGui -lQtCore 

claus-kleins-macbook-pro:build clausklein$ cmake --version
cmake version 2.8.10.2


This are my input values:
## message(EXTRA_LIBS=${EXTRA_LIBS})   # EXTRA_LIBS=/usr/lib/libpthread.dylib/usr/lib/libcrypto.dylib
## message(EXTRA_LIBS="${EXTRA_LIBS}") # EXTRA_LIBS=/usr/lib/libpthread.dylib;/usr/lib/libcrypto.dylib

And this is a sniped of my CMakeLists.txt file:

# create LIBS and LDFLAGS list
foreach(_lib ${EXTRA_LIBS})
    get_filename_component(_lib_name ${_lib} NAME_WE) 
    string(REGEX REPLACE "^lib" "" _name ${_lib_name})
    list(APPEND LIBS "-l${_name} ")
    get_filename_component(_lib_dir ${_lib} PATH) 
    list(APPEND LINKFLAGS "-L${_lib_dir} ")
endforeach()
list(REMOVE_DUPLICATES LIBS )
list(REMOVE_DUPLICATES LINKFLAGS )

# trace
message( STATUS SNMP_PP_LIBS="${LIBS}")
message( STATUS SNMP_PP_LDFLAGS="${LINKFLAGS}")
#
# -- SNMP_PP_LIBS="-lpthread -lcrypto "
# -- SNMP_PP_LDFLAGS="-L/usr/lib "
# ...
## configure_file(snmp++-3.pc.in snmp++-3.pc @ONLY)
# -- Generating snmp++-3.pc file for pkg-config ...
#
# Libs.private: @LIBS@ @LINKFLAGS@
# ... expands to:
# Libs.private: -lpthread ;-lcrypto  -L/usr/lib
#                                    ^
#                 How can I prevent this?



Can anyone please help?

Thanks in advance
Best Regards
