I have a cmake project where I want to add a class containing the matlab engine. For compiling it I need to include two libraries eng and mx, which I do by adding
target_link_libraries( ${TARGET} /usr/local/MATLAB/R2013b/bin/glnxa64/libeng.so)
target_link_libraries( ${TARGET} /usr/local/MATLAB/R2013b/bin/glnxa64/libmx.so)
to my CMakeLists.txt file.
However there are also lots of other old versions of libraries in /usr/local/MATLAB/R2013b/bin/glnxa64/, which seem
to be automatically added to the path as well when calling the above command. I think this causes the compiler to not find my
normal libraries anymore and produces an error.
How can I include only the two above libraries, and not all the others in the glnxa64 folder?
The warning shown after running cmake . :
CMake Warning at CMakeLists.txt:23 (add_executable):
Cannot generate a safe runtime search path for target CCDWidget because
files in some directories may conflict with libraries in implicit
directories:
runtime library [libboost_program_options.so.1.49.0] in /usr/lib may be hidden by files in:
/usr/local/MATLAB/R2013b/bin/glnxa64
runtime library [libboost_system.so.1.49.0] in /usr/lib may be hidden by files in:
/usr/local/MATLAB/R2013b/bin/glnxa64
runtime library [libboost_filesystem.so.1.49.0] in /usr/lib may be hidden by files in:

runtime library [libboost_regex.so.1.49.0] in /usr/lib may be hidden by files in:
/usr/local/MATLAB/R2013b/bin/glnxa64
Some of these libraries may not be found correctly.
And the error message during linking:
Linking CXX executable CCDWidget
/usr/lib/x86_64-linux-gnu/libharfbuzz.so.0: undefined reference to `FT_Face_GetCharVariantIndex'

Below is my full CMakeLists.txt file. Lines commented out with two ## are alternatives that I tried before and didn't solve my problem.
I also added LINK_PRIVATE to the target_link_libraries command as shown in the code below, which didn't make a difference.
The option PRIVATE alone seems to be not accepted by my cmake version, as it changed the error meassage to
/usr/bin/ld: cannot find -lPRIVATE
collect2: error: ld returned 1 exit status
When the #eng line is commented out, the compilation and linking works without errors
(when calling the matlab engine is also commented out in Readout.cpp), so the error must be produced by that line.
