This
freetype
library in Crystal release on Windows is a static library and that implies any dependencies offreetype
also need to be exported to the downstream project which consumesfreetype
.If following the steps from
https://index.ros.org/doc/ros2/Installation/Windows-Development-Setup/
, there is no problem because no other unexpected libraries in CMAKE search path. However, for example,ZLib
just happens to be in the CMAKE search path, thenfreetype
will be intellegently try to discover and link againstZLib
and however the freetype CMake config was not exposing its dependencies to the downstream projects consumingfreetype
.In order to make the build more predictable for different environment, I added the flags to explicitly disable all the optional dependencies discovery.
UPDATED: Here is a example of the build error when running into this.
