[RQt-devel] windows cmake build issue

[Fabrice Nicol]

Hi there,

I tried to build the source under windows XP.

I followed source code indications and checked agains the cranvas download
web page, so neither paths nor prerequisites seem to be at issue, as far as
they are indicated in these references.

The issue revolves around a persistent cmake inability to locate Qt5Core.
Although this sounds natural with the Qt4.8.4 the cranvas site indicates,
it comes more of a surprise when Qt5.2.0 has been installed and pathed to.

I'd be grateful for hints, if any, being much more of an autotools guy than
a cmake wizard.

Below is the console ouptut.

PS: currently using the linux distro for professional applications with
nice reception by users, windows porting would smooth things out for them.

CMake Warning at CMakeLists.txt:9 (find_package):
  By not providing "FindQt5Core,.cmake" in CMAKE_MODULE_PATH this project
has
  asked CMake to find a package configuration file provided by "Qt5Core,",
  but CMake did not find one.

  Could not find a package configuration file provided by "Qt5Core,"
  (requested version 5.2.0) with any of the following names:

    Qt5Core,Config.cmake
    qt5core,-config.cmake

  Add the installation prefix of "Qt5Core," to CMAKE_PREFIX_PATH or set
  "Qt5Core,_DIR" to a directory containing one of the above files.  If
  "Qt5Core," provides a separate development package or SDK, be sure it has
  been installed.
