CMP0037: Extend policy to reserved names and custom targets
Teach add_custom_target to check the policy too. Extend the policy to disallow reserved target names that we use for builtin targets like "all". Extend the RunCMake.CMP0037 test to cover these cases.

CMP0037
|
||||
-------
|
||||
|
||||
Target names should match a validity pattern.
|
||||
Target names should not be reserved and should match a validity pattern.
|
||||
|
||||
CMake 2.8.12 and lower allowed creating targets using :command:`add_library` and
|
||||
:command:`add_executable` with unrestricted choice for the target name. Newer
|
||||
cmake features such as :manual:`cmake-generator-expressions(7)` and some
|
||||
CMake 2.8.12 and lower allowed creating targets using :command:`add_library`,
|
||||
:command:`add_executable` and :command:`add_custom_target` with unrestricted
|
||||
choice for the target name. Newer cmake features such
|
||||
as :manual:`cmake-generator-expressions(7)` and some
|
||||
diagnostics expect target names to match a restricted pattern.
|
||||
|
||||
Target names may contain upper and lower case letters, numbers, the underscore
|
||||
character (_), dot(.), plus(+) and minus(-). As a special case, ALIAS
|
||||
targets and INTERFACE library targets may contain two consequtive colons.
|
||||
|
||||
The OLD behavior for this policy is to allow creating targets which do not match
|
||||
the validity pattern. The NEW behavior for this policy is to report an error
|
||||
Target names reserved by one or more CMake generators are not allowed.
|
||||
Among others these include "all", "help" and "test".
|
||||
|
||||
The OLD behavior for this policy is to allow creating targets with
|
||||
reserved names or which do not match the validity pattern.
|
||||
The NEW behavior for this policy is to report an error
|
||||
if an add_* command is used with an invalid target name.
|
||||
|
||||
This policy was introduced in CMake version 3.0.0. CMake version
