2. Overview
与主流的工程一样，QGIS采用CMAKE编译。以下是建立所需依赖关系的总结：
所需的构建工具：
- CMake >= 2.8.6
- Flex >= 2.5.6
- Bison >= 2.4
所需的构建依赖项：
- Qt >= 5.3.0
- Proj >= 4.4.x
- GEOS >= 3.4
- Sqlite3 >= 3.0.0
- SpatiaLite
- libspatialindex
- GDAL/OGR >= 2.0
- Qwt >= 5.0 & (< 6.1 with internal QwtPolar)
- expat >= 1.95
- QScintilla2
- QCA
- qtkeychain (>= 0.5)
可选依赖关系：
- for GRASS providers and plugin - GRASS >= 6.0.0. QGIS may be compiled with GRASS 6 or GRASS 7. It can also be compiled with both GRASS versions in a single build but only if QGIS is not installed with rpath. The desired GRASS version is chosen on runtime by setting LD_LIBRARY_PATH or PATH.
- for georeferencer - GSL >= 1.8
- for postgis support - PostgreSQL >= 8.0.x
- for gps plugin - gpsbabel
- for mapserver export and PyQGIS - Python >= 3.3
- for python support - SIP >= 4.12, PyQt >= 5.3 must match Qt version, Qscintilla2
- for qgis mapserver - FastCGI
- for oracle provider - Oracle OCI library
间接依赖：
GDAL支持的一些专有格式（如ECW和MrSid）需要专有的第三方库。确保GDAL 构建正确并支持格式，QGIS不需要自己重新构建这些格式。
