In general, CMake functions use the following naming convention:
command names are all lowercase with words separated by underscores
For example:
ExternalData_add_test(...)
ExternalData_add_target(...)
ExternalData_expand_arguments(...)
Some CMake modules use a different notation:
ExternalProject_Get_Property(...)
ExternalProject_Add_StepTargets(...)
ExternalProject_Add_Step(...)
ExternalProject_Add_StepDependencies(...)
ExternalProject_Add(...)
FetchContent_Declare(...)
FetchContent_MakeAvailable()
FetchContent_GetProperties(...)
FetchContent_Populate(...)
Are there more conventions? Is it possible to make the documentation more consistent? I suggest adding naming conventions to Help/dev/documentation.rst under the section Style: CMake Command Signatures
Function names are case insensitive. For my own projects i use the same casing as used by the CMake documentation. For consistency I am considering to use the lowercased version, instead - unless i am overlooking something.
