[Feature Request] Allow passing of CMake flag to disable example build

[aentinger]

So far I've not been able to find one, or I've overlooked it :bow: .

Note: This is a concern when installing mp-units system-wide via

git clone https://github.com/mpusz/mp-units && cd mp-units && \
mkdir build && cd build && \
cmake -DMP_UNITS_AS_SYSTEM_HEADERS=ON -DMP_UNITS_BUILD_LA=OFF .. && \
make -j8 && \
sudo make install

and especially painful if run on a not-powerful embedded target, i.e. here.

Please see:

• https://mpusz.github.io/mp-units/2.1/getting_started/installation_and_usage/#installation-and-reuse
• https://mpusz.github.io/mp-units/2.1/getting_started/faq/#why-dont-we-have-cmake-options-to-disable-the-building-of-tests-and-examples

I hope it helps :-)

Thank you, but yes/no. I don't really care about Conan at this point in time. I'll just have to maintain a patch for the required CMakeLists.txt files myself.

Just use 'src' subdirectory.

This is a working solution :+1: (It has its drawbacks, since I can't specify mp-units as a ROS dependency for ament_cmake which has further implications, but at least I can build w/o examples on my embedded target. Good enough for now.)
