Use installed CMake instead of embedded one in Visual Studio 2017 - cmake

Question

I've a CMake project. It uses the last version of Boost (1.66.0) that are supported in actual installed CMake version (3.11.0 rc2) but not in previous one (3.10.0).
If I build it with CMake from command line, everything is ok, but if I open the folder in Visual Studio 2017, I obtain an error because Visual Studio uses a CMake installation that's not mine, but is the one embededed with its installation: in the output panel the full cmake command path is C:\PROGRAM FILES (X86)\MICROSOFT VISUAL STUDIO\2017\COMMUNITY\COMMON7\IDE\COMMONEXTENSIONS\MICROSOFT\CMAKE\CMake\bin\cmake.exe, that's not the version that I've installed and it is also the previous version (3.10.0) so project it does not compile.
Is there a way to tell to Visual Studio to use my CMake installation instead of its one?

Answer 1

No (with the exception of the trick shown below), you can only use your own CMake version when doing Visual C++ for Linux Development with CMake on a remote machine with a CMakeSettings.json like this:
{
"name": "Linux-Debug",
"generator": "Unix Makefiles",
"remoteMachineName": "${defaultRemoteMachineName}",
"configurationType": "Debug",
"remoteCMakeListsRoot": "/var/tmp/src/${workspaceHash}/${name}",
"cmakeExecutable": "/usr/local/bin/cmake",
"buildRoot": "${env.LOCALAPPDATA}\\CMakeBuilds\\${workspaceHash}\\build\\${name}",
"remoteBuildRoot": "/var/tmp/build/${workspaceHash}/build/${name}",
"remoteCopySources": true,
"remoteCopySourcesOutputVerbosity": "Normal",
"remoteCopySourcesConcurrentCopies": "10",
"cmakeCommandArgs": "",
"buildCommandArgs": "",
"ctestCommandArgs": "",
"inheritEnvironments": [ "linux-x64" ]
}
But you can give support to a feature request utilizing the cmakeExecutable property more generally:
CMakeSettings.json: cmakeExecutable only working for remote machines
Some Background Information
As with #usr1234567's answer Visual Studio 2017 uses - as of Version 15.6.1 - it's own branch of CMake:
https://github.com/Microsoft/CMake/tree/cmake-daemon
That the version shipped with Visual Studio 2017 is not an official build you can see be calling:
> "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake" --version
cmake version 3.10.18011902-MSVC_2
So I'm not sure if a official CMake release would nicely/fully integrate into Visual Studio 2017. But there is already a request to merge the Microsoft specific changes back to CMake's main branch:
Issue #16998: Visual Studio 2017: merge Microsoft cmake-daemon branch to master
EDIT: Possible Workaround
A short test has shown that I could trick Visual Studio into taking your installed version by doing a simple renaming of Visual Studio's CMake folder and replacing it a symbolic link to your systems installed CMake version (from a cmd prompt with a administrative rights):
> ren "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake" _CMake
...
> mklink /d "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake" "C:\Program Files\CMake"
...
Warning: You have to undo this with before you update Visual Studio 2017. Otherwise the VS2017 udpate process will replace/overwrite your original CMake installation.

You have already learned from other answers that currently, that is using VS2017 15.6.6 and VS2017 15.7.0 Preview 3.0, you can not force Visual Studio to use your preferred installation of CMake.
However, you can approach your actual problem differently and work around it.
It uses the last version of Boost (1.66.0) that are supported in actual
installed CMake version (3.11.0 rc2) but not in previous one (3.10.0).
Simply, download newer version of FindBoost.cmake and install it inside CMAKE_BINARY_DIR, then point your CMakeLists.txt to prefer it:
if (CMAKE_VERSION VERSION_LESS 3.11)
# Latest FindBoost.cmake has likely been updated to detect Boost version not yet released
if (NOT EXISTS "${CMAKE_BINARY_DIR}/cmake/FindBoost.cmake")
message(STATUS "Downloading FindBoost.cmake from https://gitlab.kitware.com/cmake/ release branch")
file(DOWNLOAD
"https://gitlab.kitware.com/cmake/cmake/raw/release/Modules/FindBoost.cmake"
"${CMAKE_BINARY_DIR}/cmake/FindBoost.cmake")
endif()
list(INSERT CMAKE_MODULE_PATH 0 ${CMAKE_BINARY_DIR}/cmake)
endif()
I've used this approach for quite a while now for Boost.GIL, https://github.com/boostorg/gil

Answer 3

in Visual Studio 2022, setting the cmakeExecutable option in CMakeSettings.json will make VS use your preferred cmake. (https://stackoverflow.com/a/58774277/16550663)
You can also hide the your machine-specific path using environment variable. (https://stackoverflow.com/a/72612017/16550663)

Answer 4

For Visual Studio 2015 it was not supported to use an external CMake.
Source: Marians answer to Dmitry's question / comment.
The wording in a recent blog post (January 2018)
In our effort to make sure you have access to the latest features of CMake, we have upgraded the version of CMake that ships with Visual Studio from 3.9 to 3.10.
doesn't indicate this has not changed.
Update: There as a recent preview from Visual Studio including CMake 3.11.
