Build failure due to ‘OCCA_MAX_ARGS’ not declared

[pdhahn]

I just did a git pull on origin/master and now I am at commit 3cba0841b2b87678da53e0b311cb7e162d781181.

I cleaned my build area, did cmake configure / generate as usual. My cmake configuration is unchanged from my last successful build.

Build now shows this error:

My platform is Linux Mint 21 on Intel CPU hardware with g++ version 11.4.0. This is unchanged from my last successful build.

Can you check your include/occa/defines/ folder to see if there is an outdated compileDefines.hpp. This is sometimes leftover from a previous GNUMake build but is in the .gitignore and can cause headaches in subsequent CMake builds.

I will open an issue to remove this file when make clean is called and delete it from the .gitignore since it has caused headaches for several people recently.

Yes removing this file cured the issue. Thanks!
