Help: Clarify behavior of if() basic expressions (!6768) · Merge requests · CMake / CMake

Craig Scott requested to merge craig.scott/cmake:doc-if-env-var into master Nov 28, 2021

Changes are in response to the following forum discussion: https://discourse.cmake.org/t/if-something-strikes-again/4330

The behavior of if(ENV{some_var}) is potentially unexpected. It is also easy to miss the effect of CMP0054 when the expression is a quoted string.

Backport: release
Topic-rename: doc-if-basic-expressions
