[QGIS-Developer] Mac build broken d0e927a

[Larry Shaffer]

Hi Gary,

Upon a clean build with CMake 3.10.0 (latest in Homebrew since end of
November), I get the same error as you reported. I did the following to get
back to a working compilation toolchain (assuming you are using CMake from
Homebrew):

brew rm -f cmake

# the following is CMake at 3.9.6, with available 'bottled' binaries, i.e.
no need to build from source:
brew install
https://raw.githubusercontent.com/Homebrew/homebrew-core/33ed355cfc5ae6c64bb70f80b74876b58d6d413a/Formula/cmake.rb

# this brings 3.10.0 in again
brew upgrade cmake

This leaves you with 3.10.0 'cmake' utility discoverable on PATH (assuming
/usr/local/bin is on PATH) and 3.9.6 available from:
/usr/local/Cellar/cmake/3.9.6/bin/cmake

You can use `brew switch cmake 3.9.6` if you want 3.9.6 on PATH. I didn't
do that, but instead created a new CMake configuration in Qt Creator
(assuming you are using that) and applied it to the kit I am using to build
QGIS 3.

I reported upstream at CMake that this issue has returned:
