Re: [CMake] How to use Ninja on Windows with MSVC?

[Michael Jackson]

Cool tip. Didn’t know that. I should compact my script a bit. I do that for the 
Intel Fortran compiler that we use but didn’t think of it for the vcvarsall.bat 
file.

1: Ninja needs to be on your path

1 can be solved in a few different ways. The brute force is to edit the system 
path variable and place the folder containing Ninja into the system path. I do 
NOT recommend doing this. Repeat. DON'T DO IT. You can edit your "User" PATH 
environment variable and add to the PATH. This is the more recommended way but 
a bit tedious to get into that dialog box to adjust. We will come back to this..

For 2, use the "Visual Studio Command Prompt" which has all the paths to the 
compilers setup for you. Now the question becomes, how to combine 1 and 2. My 
own solution (which is far from optimal, but works) is that I setup my own 
"short cut" to a command prompt that launches my own custom .bat file that sits 
on my desktop. In that .bat file is basically a copy of the vcvarsall.bat file 
and then I add to that my own specific PATH values for things like Qt, hdf5, 
cmake, ninja that on located on my system. I keep both the shortcut and the 
.bat file on my desktop so all I need to do is double click to get a correctly 
configured command prompt for my dev environment. If a version of something 
changes I just edit the .bat file and I am ready to go. You can then also do 
"cmake-gui.exe ." from inside a build folder to have CMake-Gui launch with all 
the correctly identified compilers. 

 

For this option, you can use the batch command, "call", to read in the 
environment of another ".bat" script, so that you do not have to make copies of 
the vcvarsall.bat files.  As long as you are not using "setlocal" in a script, 
then the environment variables will propagate up to the caller.

 

 For example your script can have (for VS 2015) :

call "%VS140COMNTOOLS%VsVars32.bat"  

 

and the add lines setting additional PATH values.

 

Regards,

 

Juan

 

 


I am happy to share the .bat file if you are interested. I have it updated for 
VS2017 at the moment but have been doing it this way since VS2013.

Re: [CMake] How to use Ninja on Windows with MSVC?

[Robert Dailey]

Thanks everyone. I fully understand about compilers being on PATH or
setting the CMAKE__COMPILER variables. However, what is really
important is the system introspection done by CMake to find the IDEs
when you select the visual studio generators. I was hoping that logic
could be shared. This would save a lot of work in setting up
environment and/or hunting down vcvars batch files.

In addition to the other suggestions about using a MSVC command prompt (which 
work just fine for manual builds), Here’s what I’ve done when needing to 
automate the build using powershell:


Invoke-BatchFile "${env:ProgramFiles(x86)}\\Microsoft Visual 
Studio\\2017\\Community\\VC\\Auxiliary\\Build\\vcvarsall.bat" x86_amd64
Get-ChildItem env:* | Sort-Object name


…which invokes the vcvarsall batch and imports all of the environment vars that 
were set by that invocation. vcvarsall is provided exactly for the purpose of 
setting your env for building and it supports a few different arch arguments to 
select the right toolchain.

HTH,
Mike

The easiest way is to launch a CMD with the correct development environment 
(see for example 
https://docs.microsoft.com/en-us/dotnet/framework/tools/developer-command-prompt-for-vs).

Re: [CMake] How to use Ninja on Windows with MSVC?

[Haocheng Liu via CMake]

You can run `CMake -GNinja ` in a visual studio
command line prompt where It could find the right C/C++ compiler via the
environment. Normally you can find the command line prompt in the windows
menu.
