[Buildroot] [PATCH] cppcms: fix build on machines with libgpg-error installed

[Thomas Petazzoni]

In configuration where target architecture == host architecture, and
libgpg-error is installed system-wide with development files, the build
of cppcms fails with:

/home/test/buildroot/output/host/usr/bin/x86_64-amd-linux-gnu-g++  --sysroot=/home/test/buildroot/output/host/usr/x86_64-buildroot-linux-gnu/sysroot  -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Os -Wall -Wextra  -DNDEBUG   CMakeFiles/base64_test.dir/tests/base64_test.cpp.o  -o base64_test  -L/home/test/buildroot/output/host/usr/x86_64-buildroot-linux-gnu/sysroot/usr/lib -Wl,-rpath,/home/test/buildroot/output/build/cppcms-1.0.5:/home/test/buildroot/output/build/cppcms-1.0.5/booster:/usr/lib -rdynamic libcppcms.so.1.0.5 booster/libbooster.so.0.0.3 -lpthread /home/test/buildroot/output/host/usr/x86_64-buildroot-linux-gnu/sysroot/usr/lib/libpcre.so /home/test/buildroot/output/host/usr/x86_64-buildroot-linux-gnu/sysroot/usr/lib/libgcrypt.so /home/test/buildroot/output/host/usr/x86_64-buildroot-linux-gnu/sysroot/usr/lib/libdl.so /home/test/buildroot/output/host/usr/x86_64-buildroot-linux-gnu/sysroot/usr/lib/libz.so

The problem comes from the
"-Wl,-rpath,/home/test/buildroot/output/build/cppcms-1.0.5:/home/test/buildroot/output/build/cppcms-1.0.5/booster:/usr/lib"
option, which tells the linker to search for libraries in /usr/lib.

This commit fixes that by asking CMake to not add any rpath when
building cppcms.

I'm unable to reproduce this issue since I don't have /usr/lib at the end of
"-Wl,-rpath" line.

Even trying to execute the command line manually it build fine here. (I checked
that libgpg-error is installed).

Weird...

Otherwise ok for me.

Do you have libgpg-error-dev installed as well?
