Maybe open a pull request so that this can be more easily integrated?

@amdsobhy I second this. Please open a pull request with the suggested change.

will do

This is still failing for QNX Neutrino. CMake OS flag as of today (see here) is QNXNTO instead of QNX. Please add: if(WIN32 OR APPLE OR QNX OR QNXNTO)

Hi @pablorcum, you need to add this in your toolchain file set(QNX TRUE) set(CMAKE_SYSTEM_NAME QNX)

You can take a look at the toolchain file here https://github.com/asobhy-qnx/bullet3/blob/master/qnx.nto.toolchain.cmake as a reference.

Thank you, @asobhy-qnx. That's right, I had added set(QNX 1) to my QNX toolchain file, which had already set(CMAKE_SYSTEM_NAME QNX), and it works. But it is a workaround.

CMake already adds automatically set(QNXNTO 1) if it detects crosscompiling to QNX as shown here. No need to add any environment variable in the toolchain file. Therefore, and to be compliant to CMake documentation and so that it works off-the-shelf, QNXNTO should be added to FindThirdpartyBoost.cmake.

Thank you for the clarification. It does seem like the better way to do it. I would like to test it then maybe change it to QNXNTO instead
