Polyspace Test xUnit tests fails to compile: fatal error: gtest/gtest.h

What parameter controls the C++ include file search path for my gtest test file?

Creating the project file with the python interface, I used (full python program listing attached):

buildConf.ExternalTestsBuildOptions.IncludePaths.add("/nix/store/pqyrsjax8n0wb4dxap66pf6ix6qdz34a-gtest-1.12.1-dev/include/")

This command attempts to build and run the test (mkproj.py attached):

python mkproj.py

That path does not seem to be included into the command line that compiles my test program:

### Building Polyspace Test xUnit tests
### Building for host
### Building 'testbin_sil'
### Using toolchain: GNU gcc/g++ | gmake (64-bit Linux)

The "workaround" is to put it into the plain buildConfig.IncludePaths. Perhaps this is not a workaround and is the proper placement.

What is the intended purpose of ExternalTestsBuildOptions?

Hello,

The main issue was actually adding the GTest test under "Polyspace xUnit Test" instead of "External Test Files".

The ExternalTestsBuildOptions setting is specifically intended to support external xUnit test frameworks—such as GTest—in addition to the Polyspace xUnit Test Framework. This allows you to integrate and run tests from other frameworks within the Polyspace environment. You can find more details in the documentation here:

https://www.mathworks.com/help/polyspace_test/ug/run-external-cc-tests-in-polyspace-platform-user-interface.html?s_tid=srchtitle_support_results_3_gtest

Let me know if you need further clarification!
