missing fPIC from examples and tests

[kallisti5]

CMAKE_POSITION_INDEPENDENT_CODE:BOOL=ON

global fPIC is on, however..

-fPIC only shows up on the shared library. The build fails due to fPIC issues between boost and various matrix components.

Compiling, disabling the tests and examples fixes the wall of fPIC errors...

cmake -S. -Bbuild -DBUILD_LIB_TESTS=OFF -DBUILD_LIB_EXAMPLES=OFF
cmake --build build -j16

[deepbluev7]

That's curious, I don't think we do anything special on the package, that should cause this. Definitely not intentional.

[kallisti5]

yeah.. it's a weird one. I can "force" fPIC via CMAKE_CXX_FLAGS/CMAKE_LD_FLAGS in the examples to solve it there.

cmake 3.19.4
