When you have built Asyn and properly configured it in your configure/RELEASE file the path to the Asyn module’s include subdirectory is visible as one of the -I parameters to the /usr/bin/g++ command. I don’t see that in your output above, so that either means that you have a typo in the path you used, or your Asyn module hasn’t been built properly and doesn’t have an include directory (the build system will not provide a -I option to a path which doesn’t exist).

I would run the commands below to check your installation, this is what they give on my system:

$ grep ASYN configure/RELEASE 
ASYN=/C2/ioc-modules/build/ASYN/4.40-C2-2+PH-014
$ ls /C2/ioc-modules/build/ASYN/4.40-C2-2+PH-014
asyn/		lib/	      testApp/		       testFtdiApp/
bin/		LICENSE       testArrayRingBufferApp/  testGpibApp/
configure/	Makefile      testAsynPortClientApp/   testGpibSerialApp/

For CentOS8 you may also need to disable building the streamApp subdirectory because if you have configured Asyn with USE_TIRPC=YES the IOC built in that StreamDevice directory will fail to link (it also needs to be linked with the libtirpc.so library when Asyn uses it). Make this change to your StreamDevice installation to do that:
