Cannot configure with cmake (Invalid character escape '\m' in Modules/FindDoxygen.cmake:955)

[Дилян Палаузов <dilyan.palauzov@xxxxxxxxx>]

Hello,

with ccmake 3.12.2, cmake 3.13.1 and libssh 0.9.0, when I do “ccmake .”, it prints the error:

CMake Error at build/CMakeDoxygenDefaults.cmake:471 (set):
   Syntax error in cmake code at

/src/libssh-0.9.0/build/CMakeDoxygenDefaults.cmake:471

   when parsing string

\makeindex

   Invalid character escape '\m'.
 Call Stack (most recent call first):
   /usr/local/share/cmake-3.12/Modules/FindDoxygen.cmake:955 (include)
   doc/CMakeLists.txt:40 (doxygen_add_docs)

I have WITH_INTERNAL_DOC (compile Doxygen documentation) OFF

The consequence is, that the configure phase cannot generate build files.

Regards
  Дилян
