Describe the bug
When MATPLOTPP_BUILD_EXPERIMENTAL_OPENGL_BACKEND=ON I get the following error during cmake configure.
CMake Error: install(EXPORT "Matplot++Targets" ...) includes target "matplot_opengl" which requires target "glad" that is not in any export set.
In my case, find_package(GLAD) does not find anything so FetchContent is used to download glad. Cmake is complaining that matplot_opengl depends on a local target, glad, that won't be installed.
I suspect the solution is to append it to the TARGETS list if built locally, but there may be some other subtleties I'm not considering.
Steps to Reproduce
# This is part on Arch Linux AUR build() step
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX="$pkgdir/usr" \
-DBUILD_SHARED_LIBS=ON \
-DMATPLOTPP_BUILD_EXPERIMENTAL_OPENGL_BACKEND=ON \
-DMATPLOTPP_BUILD_EXAMPLES=OFF \
-DMATPLOTPP_BUILD_TESTS=OFF \
Output
```console
CMake Error: install(EXPORT "Matplot++Targets" ...) includes target "matplot_opengl" which requires target "glad" that is not in any export set.
```
