[SergioRAgostinho]

This PR enables building pcl_simulation + associated tools and Qt+VTK things on our CI.

Suggested change

	find_package(glew)
	find_package(glew CONFIG)

[larshg]

It uses the findglew file first atm:
https://dev.azure.com/PointCloudLibrary/pcl/_build/results?buildId=17217&view=logs&j=cd6332f9-d180-53f5-8d9a-3b5d9c3252a2&t=85d62bd5-4d0c-5e0e-700b-d959df91e277&l=101

[larshg]

Alternatively just use the the original? The FindGLEW.cmake, finds glew with config search internally.

[larshg]

Can't GLEW be found, if you just use the original find_pacakge(GLEW) ?

Else you need to keep the:

if(APPLE)
  find_pacakge(glew CONFIG)
ELSE()
  find_pacakge(GLEW)
ENDIF()

[SergioRAgostinho]

It can, but it's incorrect. The package comes with links to non-existing locations in my setup.

leaving it here to see what happens if we remove pkg-config

[SergioRAgostinho]

the macos jobs now take more than the gcc stages to build.

Please go ahead with the merge. Also, please merge the release commit and start the release pipeline.

[SergioRAgostinho]

I've just cleaned up the commits and rebased. I will wait for build completion before merging just to be sure.
