Building plugins on Ubuntu 22.04 fails

[jvasi]

The following compilation issue occurs:

[ 57%] Building CXX object CMakeFiles/torch2trt_plugins_test.dir/plugins/src/tests.cpp.o
/home/..../dev/torch2trt/plugins/src/tests.cpp:2:10: fatal error: catch2/catch_all.hpp: No such file or directory
    2 | #include <catch2/catch_all.hpp>
      |          ^~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
gmake[2]: *** [CMakeFiles/torch2trt_plugins_test.dir/build.make:76: CMakeFiles/torch2trt_plugins_test.dir/plugins/src/tests.cpp.o] Error 1
gmake[1]: *** [CMakeFiles/Makefile2:867: CMakeFiles/torch2trt_plugins_test.dir/all] Error 2
gmake: *** [Makefile:166: all] Error 2

The problem seems to be that the catch2 version installed on Ubuntu 22.04 is 2.13.8-1 whereas trt2pose expects version 3 instead. However, no version check is performed.

Easiest way to fix the issue is by disabling the tests. The only way to disable running the tests is editing torch2trt/CMakeLists.txt and commenting out the tests by, e.g. commenting out the following line:

...
# BUILD TESTS
find_package(Catch2 QUIET)
...
