Build OpenSim Creator for downstream C++ projects

build_osc_install.sh

# !!!! WARNING: THIS ISN'T OFFICIAL IN ANY WAY: DON'T COME CRYING TO ME IF YOUR C++ BREAKS !!!!

# # Before: get source code and enter directory:
#
# git clone https://github.com/ComputationalBiomechanicsLab/opensim-creator
# cd opensim-creator/

build_type=Release
build_dir=${PWD}/build
install_dir=${PWD}/install

# Build + install dependency libraries + headers
cmake -G Ninja -S third_party/ -B ${build_dir}/third_party -DCMAKE_BUILD_TYPE=${build_type} -DCMAKE_INSTALL_PREFIX=${install_dir} -DBUILD_TESTING=OFF
cmake --build ${build_dir}/third_party

# Build + install libopensimcreator library + headers
cmake -G Ninja -S . -B ${build_dir} -DCMAKE_BUILD_TYPE=${build_type} -DCMAKE_INSTALL_PREFIX=${install_dir} -DBUILD_TESTING=OFF
cmake --build ${build_dir} --target install

# # Cleanup (optional)
# rm -rf ${build_dir}

# Usage in downstream projects:
#
#     In your downstream CMakeLists.txt:
#
#         find_package(opensimcreator REQUIRED)
#         # (other stuff)
#         target_link_libraries(downstream_project PRIVATE opensimcreator)  # link to it
#
#     In your build script, depending on how/where you installed it:
#
#         cmake -S downstream_project -B build_dir -DCMAKE_PREFIX_PATH=${install_dir}
#         # (i.e. tell cmake where to find the install directory)
#
#     In your C++:
#
#         #include <libopensimcreator/SOME_HEADER_FROM_OPENSIMCRETOR>
#         // see OpenSim Creator's source code for inspiration: you probably want to create
#         // an `osc::OpenSimCreatorApp` and give it your own implementation of an `osc::Tab`
#         // to show your own UI.
#         //
#         // e.g. as osc.cpp does for the `osc` top-level executable
