Qt Creator: show all project files in stocked CMake plugin in Hackers way

qtc-display-all-project-files.md

Not a question, just a life-hack :-)

Changes, that allows showing all project files in project view is discarded. Clarification that Project View is not a Project View but Build System View is added to the documentation. So, now there is no way to propagate CMakeProjectManager2 changes to the upstream at all.

But we can still display all files using stock plugin and existing functionality. Just hack it using fake CMAKE_TOOLCHAIN_FILE...

Idea:

• using file(GLOB_RECURSE ...) scan project tree for files
• create fake target ALL_PROJECT_FILES with this files
• put it to the fake toolchain file to avoid modification of the original CMakeLists.txt
• pass fake toolchain file to the cmake executable via Kit CMake properties...

Solution:

• https://gist.github.com/h4tr3d/0b610a507ed42faeb3c32e2700fabb13#file-qtc-scan-all-cmake

Solution allows to configure globbing expression for scanner per build configuration. Via Kit CMake configuration it can be configured per-kit. Look into Gist for complete instruction.

Screen shot:

It can be extended to allow passing exclude globbing expression. It can be extended in any way :-)

# Open QtC :: Tools -> Options, Go to Build & Run page, Switch to the Kits page.
#   Select needed Kit and press Change... for CMake Configuration item
#   Add Parameter:

#   If you need real toolchain file, just pass it as:
