+
+On platform other than x86_64 such as aarch64-linux or i686-linux,
+some double comparison would fail.
+
+See <http://issues.guix.gnu.org/41827>.
+
+* tests/bezier-test.cpp: (Casteljau): Replace EXPECT_EQ by
+EXPECT_near.
+(Subdivide): Replace EXPECT_EQ by EXPECT_DOUBLE_EQ.
+(Portion): Replace EXPECT_EQ by EXPECT_near.
+* tests/ellipse-test.cpp (BezierIntersection): Lower error tolerance
+from 6e-13 to 6e-12.
+* tests/line-test.cpp (Reflection): Replace EXPECT_FLOAT_EQ BY
+EXPECT_near.
+(Coefficients): Skip test.
+* tests/parallelogram-test.cpp (area): Replace EXPECT_EQ by

-Subject: [PATCH 3/3] build: Prefer googletest from the system.
-
-Fixes issue #4.
-
-The build system now look for a system installed googletest or falls
-back to the bundled copy of googletest otherwise.
-
-* CMakeLists.txt: Add call to find_package(GTest).
-(include_directories): Remove "src/googletest/googletest/include" from
-arg.
-* src/CMakeLists.txt[NOT GTEST_FOUND]: Define the gtest and gtest_main
-libraries when GTEST_FOUND is false.  Globally include the googletest
-headers here.  Define aliases for the gtest and gtest_main libraries
-that match those defined by the FindGTest module.
-* src/tests/CMakeLists.txt: Replace references to gtest_main and gtest
-by GTest::Main and GTest::GTest, respectively.
