Shader cache bug fix request

[Przemog1]

Describe the bug

Shader cache doesn't always update

Steps to Reproduce

1. compile example 62_CAD
2. add some code to a builtin file used by the vertex shader of example 62, which will break HLSL compilation, but not C++ compilation. For example in the file nbl\builtin\hlsl\math\equations\quadratic.hlsl add:

#ifdef __HLSL_VERSION
fjlksad;fjslakdfj
#endif

3. delete shader cache file and compile again

Expected vs observed behavior

After step 2. compilation should fail, but it doesn't and changes to the nbl\builtin\hlsl\math\equations\quadratic.hlsl take no effect..
After step 3. compilation fails, as it should.

This bug doesn't effect every file, for example I couldn't reproduce this bug with nbl\builtin\hlsl\math\equations\limits.hlsl.
