may need to replace ignition- with gz- in the following script to fix some tests:

• https://github.com/ignitionrobotics/ign-cmake/blob/gz_cmake_project/examples/test_core_child_requires_core_no_deps.bash

done in e54db0d and added an extra fix to the pkg-config file name in 12be647

I just noticed there is an ignition- that should change to gz- on the following line, but there's also a super weird 1.1 that makes no sense to me

• https://github.com/ignitionrobotics/ign-cmake/blob/gz_cmake_project/cmake/pkgconfig/ignition-component.pc.in#L7

the 1.1 is also in cmake/pkgconfig/ignition.pc.in

I think we can remove it

Thanks, @scpeters , done in ccc12e3

Be wary that changing the project names will cause regex replaces removing ignition to no-op, which would be a bug (at least as far as the rationale for doing the regex replace is)

I found one place where this happens, but I don't think I got them all:

• gz-cmake/cmake/IgnConfigureProject.cmake

  Line 60 in 5adbd46

  string(REGEX REPLACE "ignition-" "" IGN_DESIGNATION ${IGN_DESIGNATION})

regex replaces removing ignition to no-op

Good point, removed in a477d3b since this PR will go along all downstream project name changes anyway.

Ah that broke some test cases. Reverted in 73ef90e. We can address that in follow-up PRs.
