CMakeRPathIllustration
======================
Small project illustrating how RPath features can be used within CMake
## Experiments: Disable use of @rpath and have built & installed libraries with absolute RPATH
All experiments expect the variable `CMAKE` to be set:
```bash
CMAKE=/path/to/cmake
```
### Default
```bash
EXPERIMENT=default
(rm -rf CMakeRPathIllustration-${EXPERIMENT}-build && \
rm -rf CMakeRPathIllustration-${EXPERIMENT}-install && \
ROOT_DIR=$(pwd) && \
mkdir CMakeRPathIllustration-${EXPERIMENT}-build && cd $_ && \
CMAKE_INSTALL_PREFIX=${ROOT_DIR}/CMakeRPathIllustration-${EXPERIMENT}-install && \
${CMAKE} \
-DCMAKE_BUILD_TYPE:STRING=Release \
-DCMAKE_INSTALL_PREFIX:PATH=${CMAKE_INSTALL_PREFIX} \
../CMakeRPathIllustration && \
\
make install && \
\
echo "build tree" && \
otool -L lib/MyWorld/libMyWorld.dylib && \
cat cmake/CMakeRPathIllustrationTargets.cmake | grep IMPORTED_LOCATION_RELEASE && \
cat cmake/CMakeRPathIllustrationTargets.cmake | grep IMPORTED_SONAME_RELEASE && \
\
echo "install tree" && \
otool -L ../CMakeRPathIllustration-${EXPERIMENT}-install/lib/MyWorld/libMyWorld.dylib && \
cat ../CMakeRPathIllustration-${EXPERIMENT}-install/cmake/CMakeRPathIllustrationTargets-release.cmake | grep IMPORTED_LOCATION_RELEASE && \
cat ../CMakeRPathIllustration-${EXPERIMENT}-install/cmake/CMakeRPathIllustrationTargets-release.cmake | grep IMPORTED_SONAME_RELEASE)
```
```bash
