--debug-find option gives extensive human-readable trace output for where the CMake
find_ operations are looking for files.
In most CMake projects, there are many
find_ operations, and so the
cmake --debug-find output can be overwhelming to scroll through.
The example commands refer to this CMake script:
# arbitrary other packages not of interest to trace finding find_package(Git) # package that's not working right, to debug find_package(LAPACK) # arbitrary find_* to trace variable find_library(MYLIB NAMES mylib)
Package-specific debug-find is available:
Variable-specific debug-find is available:
It’s also possible to target specific find_* calls via CMAKE_FIND_DEBUG_MODE. To debug only the finding of LAPACK:
# arbitrary other packages that are not of interest to trace finding find_package(Git) # package that's not working right, to debug set(CMAKE_FIND_DEBUG_MODE on) find_package(LAPACK) set(CMAKE_FIND_DEBUG_MODE off)
