|
# CMAKE BASICS:
|
|
# =============
|
|
# CMake is a build system generator. It doesn't compile code directly.
|
|
# Instead, it generates platform-specific build files:
|
|
# - macOS/Linux: Makefiles (then you run `make`)
|
|
# - Windows: Visual Studio project files
|
|
# - Any platform: Ninja build files (faster than Make)
|
|
#
|
|
# The workflow is:
|
|
# 1. mkdir build && cd build
|
|
# 2. cmake .. ← generates build files from this CMakeLists.txt
|
|
# 3. cmake --build . ← compiles and links the project
|
|
# 4. ./lin_simulator ← run the application
|
|
#
|
|
# Qt6 integration:
|
|
# CMake has built-in support for Qt via find_package(Qt6).
|
|
# Qt needs special preprocessing for its features:
|
|
# - MOC (Meta-Object Compiler): processes Q_OBJECT macros for signals/slots
|
|
# - UIC: compiles .ui designer files to C++ headers (we don't use these)
|
|
# - RCC: compiles resource files (icons, etc.) into the binary

# ── Qt6 auto-processing ──
|
|
# These three lines enable Qt's special preprocessors:
|
|
# AUTOMOC: automatically runs MOC on headers containing Q_OBJECT

# AUTOUIC: automatically compiles .ui files (if we had any)
|

# AUTORCC: automatically compiles .qrc resource files

# ── Find Qt6 ──
|
|
# find_package searches for Qt6 on the system.
|
|
# REQUIRED means CMake will error if Qt6 is not found.
|
|
# COMPONENTS lists which Qt modules we need:
|
|
# Widgets: GUI widgets (QMainWindow, QPushButton, etc.)
|
|
# We'll add SerialPort in Step 5 when we need device communication.
|
|

# ── Main application target ──
|
|
# qt_add_executable is Qt's wrapper around add_executable.

|
# It handles platform-specific details (macOS app bundle, Windows subsystem, etc.)

|
# ── Tests ──
|
|
# We use Qt's built-in test framework (QTest) instead of GoogleTest
|
|
# because it integrates naturally with Qt's event loop and widgets.
|
|
# QTest provides:
|
|
# - QVERIFY(condition): assert a condition is true
|
|
# - QCOMPARE(actual, expected): assert two values are equal
|
|
# - QTest::mouseClick(): simulate mouse events
|
|
# - QTest::keyClick(): simulate keyboard events
