CMake Warning (dev) at builds/cmake/Modules/FindAsciiDoc.cmake:9 (find_program):
Policy CMP0053 is not set: Simplify variable reference and escape sequence
evaluation. Run "cmake --help-policy CMP0053" for policy details. Use the
cmake_policy command to set the policy and suppress this warning.
For input:
'$ENV{PROGRAMFILES(X86)}/asciidoc'
the old evaluation rules produce:
'/asciidoc'
but the new evaluation rules produce an error:
Syntax error in cmake code at
/path/to/builds/cmake/Modules/FindAsciiDoc.cmake:13
when parsing string
$ENV{PROGRAMFILES(X86)}/asciidoc
Invalid character ('(') in a variable name: 'PROGRAMFILES'
Using the old result for compatibility since the policy is not set.
Call Stack (most recent call first):
CMakeLists.txt:193 (find_package)
This warning is for project developers. Use -Wno-dev to suppress it.
