title: ld can't find an available library
body: <p>I have a problem when linking my application, <code>ld</code> could not find an available library :</p>
  
  <pre><code>/usr/bin/ld : could not find -lVtsUtils_0.1.5d
  /usr/bin/ld : could not find -lVtsCore_0.1.5d
  /usr/bin/ld : could not find -llibmysql
  </code></pre>
  
  <p>The compile line is (found through <code>make VERBOSE=1</code>) :</p>
  
  <pre><code>/usr/bin/c++ -g CMakeFiles/Dental.dir/main.cpp.o CMakeFiles/Dental.dir/qrc_myproject.cpp.o CMakeFiles/Dental.dir/Dental_automoc.cpp.o -o ../../../bin/debug/Dentald -L/home/naccyde/Projets/myproject/lib/linux -rdynamic /usr/lib64/libQt5Widgets.so.5.6.2 -lVtsUtils_0.1.5d -lVtsCore_0.1.5d -llibmysql /usr/lib64/libQt5Gui.so.5.6.2 /usr/lib64/libQt5Core.so.5.6.2 -Wl,-rpath,/home/naccyde/Projets/myproject/lib/linux
  </code></pre>
  
  <p>But <code>ls -l /home/naccyde/Projets/myproject/lib/linux</code> show : </p>
