# IMPORTANT SHORTCOMINGS OF THIS CMAKE CONFIG FOR VISUAL STUDIO USERS
#
# Visual Studio unfortunately defaults to overriding the working directory
# for Google Test set by CMAKE.
# To fix this
#    go to Visual Studio's debug menu or tool menu,
#    choose the "options" item, and then
#    go to the "Test Adapter For GoogleTest" tab.
#
#  Set 'Working Directory' to '$(SolutionDir)'
#  (note, those are parenthesis around SolutionDir, and not braces
#   as one might become accustomed to seeing in CMake).

*********************************************************************
 IMPORTANT SHORTCOMINGS OF THIS CMAKE CONFIG FOR VISUAL STUDIO USERS
*********************************************************************

CMake fails to configure the working directory for running
tests in Visual Studio using Google Test.
Before running, got to Visual Studio's debug menu,
choose the 'options' item, and then go to the

'TestAdapterForGoogleTest' tab.
Set 'Working Directory' to '$(SolutionDir)'
(note, those are parenthesis around SolutionDir, and not braces
 as one might become accustomed to seeing in CMake).
