Добрый день!
Система: linux mint 18.1 serena. Вышла пару дней назад.
Qt брал с оф-сайта онлайн-инстайллер qt-unified-linux-x64-2.0.4-online
Получили:
Qt Creator 4.2
Qt 5.7.1
cmake 3.5.1 из оф-репов дистра
Установил из оф-репов(некоторое из списка предустановлено системой):
gcc
g++
gdb
cmake
libfontconfig1
mesa-common-dev
build-essential
libglu1-mesa-dev -y
т.е. все, что необходимо - установлено.
Создаю самый обычный проект c++ без использования qt с cmake и получаю такую ошибку:
Bash

Захожу в папку с проектом и в терминале выполняю:
Bash

Совершенно не понимаю, в чем причина. Переустанавливал qt, не помогает.
На другом ноуте снес старое qt, и поставил свежее - там все отрабатывает нормально, но там система linux mint 18 sara.
В cmake такие переменные:
Bash
CMAKE_CXX_COMPILER:STRING=%{Compiler:Executable:Cxx}
CMAKE_C_COMPILER:STRING=%{Compiler:Executable:C}
CMAKE_PREFIX_PATH:STRING=%{Qt:QT_INSTALL_PREFIX}
QT_QMAKE_EXECUTABLE:STRING=%{Qt:qmakeExecutable}
