Change Description

Added modular dependencies to CmakeLists.txt for port type folders in Drv/ and Svc/ to enable compilation with the cmake flag BUILD_SHARED_LIBS set to ON.

Rationale

These additions are necessary for users who need to build with shared libs.

Testing/Review Recommendations

Built the Ref deployment with and without the BUILD_SHARED_LIBS flag, and the deployment builds successfully. I also tested this with an external deployment and it built successfully. However, it is possible that there are additional changes required for other components/ports that were not included in the Ref or my external deployments.

Future Work

It would be a good idea to include this in the CI workflow so that this functionality is continually supported!

The cmake unit tests have a shared lib unit test that we run as part our CI checks. We should investigate why this test isn't failing

@EbenezerA99 can you move this work to devel?

[LeStarch]

@EbenezerA99 looks like we needed to update devel. See #1663. This should fix your PR as soon as it is merged.

[LeStarch]

May be an underlying CMake issue. We'll investigate.

@EbenezerA99, I just ran the following on my Linux machine and all worked as expected:

cd Ref
fprime-util generate -DBUILD_SHARED_LIBS=ON
fprime-uitl build
LD_LIBRARY_PATH=`pwd`/build-artifacts/Linux/lib

Can you elaborate the problems you are seeing in the build? Version you are running? I am trying to reproduce your issue, but it doesn't seem like an issue on Linux/devel

[EbenezerA99]

@LeStarch Sorry for not getting back to you sooner!

It also builds for me just fine on Linux, however it is not building on Darwin.

I'm using fprime-tools=3.1.1

[LeStarch]

Ok, I'll try it on Darwin

[LeStarch]

I was able to confirm this breaks on macOS. Making sure this fixes it.
