CMake Experiments

Table of Experiments

1. CMake Variables

   • Can default flags be permanently cleared?
   • Can cache variables be locally extended by shadowing them with local variables of the same name?

2. External Variables

   • Are command-line variables cache variables?
   • Can toolchains reference command-line variables?
   • Do toolchain variables persist throughout the build tree at configure time?

3. Project Directive

   • Do subsequent project() directives re-load the toolchain?

4. Target Properties

   • Is PUBLIC_HEADER transitive?
