CMAKE_INSTALL_PREFIX in Spanish on Windows

Code
1

How can I define CMAKE_INSTALL_PREFIX if Windows is in English to go to C:\program file\ and if Windows is in Spanish to go to C:\Archivos de Programas\

I think you can use $ENV{ProgramFiles} to get that path in any language. If you need the 32-bit version:

set(envvar "ProgramFiles(x86)")
set(program_files "$ENV{${envvar}}")

is needed because variable names cannot have () in them literally.

3 
set(program_files "$ENV{ProgramFiles\(x86\)}")

should also work.

I don’t think so (at least with CMP0053 set to NEW) because \( is not a recognized escape sequence. We discussed this when I implemented the policy and decided it was rare enough that the workaround was fine.

message("$ENV{ProgramFiles\(x86\)}")

gives a warning and doesn’t output what we want:

CMake Warning (dev) at D:/dev/CMExt/env_var.cmake:1 (message):

    D:/dev/CMExt/env_var.cmake:1

  when parsing string

    $ENV{ProgramFiles\(x86\)}

  syntax error, unexpected cal_SYMBOL, expecting } (19)

  Policy CMP0010 is not set: Bad variable reference syntax is an error.  Run
  "cmake --help-policy CMP0010" for policy details.  Use the cmake_policy
  command to set the policy and suppress this warning.
This warning is for project developers.  Use -Wno-dev to suppress it.

$ENV{ProgramFiles\(x86\)}

cmake_policy(SET CMP0010 NEW)
message("$ENV{ProgramFiles\(x86\)}")

gives an error and stops processing:

CMake Error at D:/dev/CMExt/env_var.cmake:2 (message):
  Syntax error in cmake code at

    D:/dev/CMExt/env_var.cmake:2

  when parsing string

    $ENV{ProgramFiles\(x86\)}

  syntax error, unexpected cal_SYMBOL, expecting } (19)

cmake_policy(SET CMP0053 NEW)
message("$ENV{ProgramFiles\(x86\)}")

gives what we want:

C:\Program Files (x86)

Oh, maybe we decided differently. In that case, carry on :slight_smile: . It’s too late to change such a minor behavior that has a small upside IMO :slight_smile: .

Thank you very much, it really helps.
